摘要
在四倍频器设计中首先对二极管进行I-V曲线、C-V曲线、等离子振荡和趋肤效应等进行计算, 完成肖特基二极管电路建模; 通过谐波和三维电磁仿真工具优化电路中各次谐波最佳阻抗值; 通过引入改进紧凑型悬置微带线震荡器(Compact Suspended Microstrip Resonators (CSMRs))滤波器, 成功将二次和三次谐波短路, 同时减小长宽比, 满足装配条件。实验表明, 四倍频在334~346 GHz频段内输出功率均大于1 mW, 最大输出4 mW, 当驱动功率为100 mW时, 最高效率可达3%。
Abstract
High frequency and power source is most important for terahtz technology, and multipliers is common electronic way. This quadrupler design is only one stage to avoid impedance mismatches between multipliers. A proposed Schottky diode model improves the accuracy of design, which has considered the behaviors of current voltage (I/V), capacitance voltage (C/V), plasma resonance, and skin effect. Theoretical analysis was carried out by using harmonic balance simulations programs and three-dimensional finite element simulation tools to find the optimum embedding impedance for a given diode. Compact Suspended Microstrip Resonators (CSMRs) minimize the length/width ratio and make short idlers at the 2nd and 3rd harmonics. The experiment shows: the quadupler works at 325~351 GHz and output power is above 1mW between 334 GHz and 346 GHz, and the highest efficiency is above 3% with input power of 100 mW.
